ANTONIU COTOLI, Q1 YABJSMA, CUBA DEE'IHOID OF AND MEANS Application filed January 13, 19122" To all toll/0m it may concern:

lie it known that l, lm'rorzio Coroner a subject of the King of Siain, residing at liilljfillil, in the Republic of Cuba, have in" vented a nev and useful Improvemen in Methods of and Means for Distributing l ments, of which the following is a specifiestion.

The invention relates to a method of and means for distributing powdered pigment as employed in the coloring of the surface of slabs, tiles or other articles Where a certain design, figure or illustration is to he reproduced in colors on the surface and which is eileoted by mixing the pigments with clay, loam coiucrete cement or any other plastic material in order to give the necessary coloring to the surface of the articles It is an object of the invention to provide a method of distributing pigments so that the coloring material is spread over an area, he outlines of which correspond to it predetermined design.

lt is e turther object of the inv-ntioii to enable the quick disti'loution of superposed layers of pigments when several pigioie of different color values are to be provided for multicolored designs.

It is also an object of the invention to provide a novel method of distributing pigments whereby geometrical figures may easily be obtained.

A further object or" the invention. aims at the provision oi improved means for dis tributing pigments.

The lnvention Iurthermore aims at the provision of a series of alates having apertures to correspond to t 1e designs to be obtained Wherethrough the pigment pernntted to flow onto the articles to be colored.

With this and other objects in View which Will become apparent as the descriptioii'proceeds, the means for carrying out the method are illustrated in the accomganying drawing, in which:

Figures l, 2, 3 and shou a series of plates haw out-out portions correspond ing to the contours of sections of: the design so that when coloring matter of (iilerent values is suecessivelj spread over the plates the desired distribution of the various pigments on the article is effected,

1m plate, for di itei wood the describ 3 portions sivcly arranged in a casing 9 in which instance the cement tiles 11 are made.

lirl ig. 5 a plate 10 indicative of any of the :t'ourv plates, 5, 6, 7 or 8 is shown in "fiche-l position, in which the distriout the powdered pigment may be to result in the figure shown in i 1 6. in, the casing 9 the tile 11 is arranged at a suitable height thereof in conformity with special requirements and subs quent thereto any one of the plates is ar- 1 21 ed on the casing.

nen a design is to be produced, first a suitable plate containing perforations is aranged on the casing and this plate is pro ded with four apertures 10 at the corners receive dowel pins 17 projecting from the 9 whereby proper arrangement oi? the pi. on the casing is insured. After the plate has been arranged in functional posit on and in true relation with the cement i re, the pigments 12, 13 are distributed over the plate and While spreading the pigment it accumulates on the cement tile and arranges itself to form an outline corresponding to the opening or perforation provided in the plate.

produce the figure shown in Fig. 6 on c ent tile 11 the plate is placed in the position occupied by the plate and thereupon a black pigment is spread over the plate which then drops through the perforations at onto the surface of the tile 11 forming thereon a layer of convenient thickness, Subsequently the plate 5 is removed and the plate- 6 is placed in functional position and white pigment is heaped on the plate to pass through the cut-out portionsb, The layer of the black pigment which has been distributed on the tile 11 by the agency oi the plate is partly covered by the layer of pigment applied through the plate 6.

Finally the same operations are executed with the plates 7 and 8 distributing the pign'ients of different color 'values over the layers arranged on the cement tile and conforming to the outlines as defined by the cut-out pt tions 0 and-(Z respectively. After the plate 8 has been removed and spreading of the pigment has been terminated a pigment of that color may be provided on the tile which is to make up the back ground and which covers portions of the surface provided with pigment for the plates 5, 6, and 8. All the colors are now distributed on the tile and form the figure as indicated by the reference characters (I. to e in Fig. 6. The tile is then ready for further treatmert to maize a lasting picture on the surface but as these steps of the method do not form part of the subject'matter of the invention, further reference thereto is seemed superfluous.

My improved method is also applicable in connection with molds for forming geometarranged surface to reproduce a desi rical figures on tiles such as is the case when for instance mosaic work 1S to be produced. As indicated in Fig. 7 a mold M is pro- "vided which is divided into, compartments 18, 19, and 2-1. If the figure defined by these compartments is to be executed in several colors a like number of plates is arranged, each of which designated by P has a cut-out portion-01' perforation f adapted to he placed in registry with a compartment of the mold. In the example shown in Figs. 7 and 8 the plate 1 has a perforation f which is iiflentical with diametrical opposite compartments such as 18 and 20 or 19 and 21. in spreading pigment over the plate 1 the former will drop through the perforation and will arrange itself on the tile miderneath the mold M in conformity with the outlines of the perforation Subse quently another plate 1 is arranged on the mold replacing the first plate and having its perforations registering with the remaining compartments of the mold so that adifferent pigment can be placed on the tile corresponding to the outline of the remaining compartments. The manner of spreading or distributing the pigment on the plates may either be effected manually orhy means of special devices. The numberof plates employed in eliecting proper distribution'o'l the pigments may be determined not only from the number of colors in which the picture is to be reproduced but also in accordance with the number of sections or portions of the figure to insure accuracy of arranging the pigments on the article. a

the invention, 0t course, is not restricted to'the execution of figures as shown in the drawing, but any design may be reproduced by the method described. It is also immaterial in which manner the plates are held ahovethe article receiving the pigments and if preferred the dowel pins may be dispensed with and other means employed to hold the parts in regist y with the article on which the figure is lto be reproduced. The drawing and specification are merely indicative of the spirit of the invention aimingat the reproduction of the designs on articles and it, therefore, do not limit myself to the exact'details of the method and to the sequence of steps as described but I claim my invention as broadly as the state of the art permits.

I claim:

1. The method of coloring a stationarily thereon, includin the step of spreading a plurality oi powdered pigments over a like number of olates spaced from said surface, each plate having perforations the outlines ofwhich correspond to the design and subjecting the surface to further treatment.

2. The method of reproducing a colored design on a surface stationai ilyarranged,

including the step of spreading a plurality of powdered pigments over a like number of plates successively arranged in registering relation to the surface receiving the design and spaced therefrom at suitable distances to permit the pigments to drop onto the surr'acewith an impact, each of said plates con taining cut-out portions coextensive with portions of the design receiving a particular color.

In means for distributing pigments in producing colored designs on a surface, a frame maintaining said surface therein in horizontal position below the upped edge of said 't'raine, a pluralit oi plates each ha ring cut-out portions coextensive with portions of the design receiving a particular color. said plates being; adapted to be placed on the top edge of said trz-Ine in spaced but registering relation to said surface, and means for maintaining the cut-out portions of said plates in f'egisii "ing relation with respect to correspon ing cf -ign portions.

4. in means for distributing pigments in producing colored designs on a surface, a stationary frame n'iaintaining said surface therein in horizontal position below the upper edge of said frame, a plurality of plates eachv having cut-out portions coextensive with portions of the design receiving a particular color, said plates being adapted to be placed on the top edge of said frame to he maintained in spaced relation to said surface and being provided With apertures adjacent to its corners, and dowel pins'upstanding from the up or edge of the frame and eX-i, tending through the apertures of the plates to maintain the latter in registering relation \rith respect to corresponding design portions.

In Witness whereof I affix my signature,

ANTONIO COTOLI.
